(c1. isn- 48) 8 Claims. 1

This invention relates to improvements in coin controlled mechanisms and is directed more particularly to coin mechanisms actuated either by a coin or coins of one size, by a coin or coins of another size, by coins of still another size, or by combinations of coins.

One object of the invention is the provision of a coin mechanism having a plurality of actuatable elements each adapted to be actuated by the impact of a coin of a different value from the others by said coins as they are moving downwardly, said mechanism including a positionable member moved by said elements in accordance with the value of the coins actuating said elements. For example, the positionable member is moved one step by each nickel, two steps by each dime, and five steps by a quarter, whereby said positionable member, in fact, sets up credits in accordance with the values of one or a plurality of coins inserted in said mechanism.

A further object of the invention is the provision of a coin controlled mechanism which is formed mainly of metal stampings which may be comparatively thin (so far as thickness is concerned) and which may be made in widths commensurate with the strength necessary in the several parts thereof. This makes it possible to produce, in mass production, a precision mechanism of comparatively few parts which is light in weight, low in cost and each of which is a duplicate of the other.

A further object of the invention is the provision of a coin controlled mechanism in which the several elements which are actuated by coins of several values all incorporate ratchet means which denne steps which nally result in the movement of a positionable member, suitable linkages between said elements and said positionable member being provided.

Another object of the invention is the provision, in a coin controlled mechanism, of a first element to be actuated by coins of one value, a second element to be actuated by coins of a diiferent value, a third element to be actuated by coins of a still different value, a positionable member moved in accordance with the value of the total coins actuating either one or all of said members, a lever pivotally connected to the first and second of said elements through means linked to the third of said elements, the pivotal connection to said rst mentioned element actuating as a pivot about which said lever moves in one direction upon the actuation of said second element, and the pivotal connection to said whether one, two or all of said elements is actuated. Y

A further object of the invention is the provision, in a coin controlled mechanism, of a plurality of elements each to be actuated by a coin of a different value, a positionable member moved by said elements, a distance proportionate to the total value of the coins entering said mechanism and actuating any or all of said elements, and a lever pivotally connected to all but one of said elements and pivotally connected to said positionable member through ratchet means forming a part of said one of said elements, none of said pivotal connections normally constituting a fulcrum until one of said elements pivotally connected to said lever is actuated by a coin, whereupon one of said pivotal connections, other than the one connected to the element actuated, becomes the fulcrum.

Yet another object of the invention is the provision, in a coin controlled mechanism, of a first element to be actuated by coins of one value, a second element to be actuated by coins of a multiple of said value, and a third element to be actuated by coins of a greater multiple of said value, said elements all being operatively connected to a common floating support, termed a postionable member, and escapement means associated with each of said elements and defining steps as follows: a rst escapement means associated with said nrst element and defining steps each representing said one value, a second escapement means associated with said second element and dening steps which are multiples oi the steps dened by said rst escapement means, and a third escapement means associated with said third element and defining steps which are a greater multiple of the steps dened by said first escapement means, whereby said positionable member is moved through a series of steps representing the values of all of the coins which .actuate said elements.

Other objects and advantages of the invention will be apparent to those skilled in the art from a study of this specincation and the accompanying drawings.

Figure 15 is a sectional view taken along the lines I5-I5 of Figure 4; and

Figure 16 shows a group of key plates representing different prices from five cents to twentyve cents so that a comparison of them may be made.

Referring rst to Figures 1, 2 and 3, which illustrate the coin controlled mechanism, a main plate 40 forms a support for the elements, some of them being positioned on one side of the plate, some of them on the other side of the plate, and some of them extending from one side of the plate to the other through openings formed therein, as will hereinafter be explained. Secured to the plate 40 on one side thereof is a U-shaped channel 4I having a passage 42 therein for quarters. This channel has flanges 43 and 44 formed on the opposite edges thereof and these flanges are spot welded to the plate 40 as at 45. The flange 43 terminates a substantial distance from the lower edge 45 of the plate 40, leaving an edge opening 47 communicating with the interior of the channel. The channel 4l has several elongated perforations, such as the perforation 48, formed therein, and on the lower end the channel has an ear 49 which is secured to the plate 4t at the point 50 with a suitable spacer therebetween. The flange 44 terminates a substantial distance from the lower ege 4S of the plate and an opening or slot 5I communicates with the interior of the channel in the same manner as it does in the channel 4l.

A shouldered screw 52 has journaled thereon a lug 53 and on the outer end of this lug is secured a rod 54 which has an upturned portion 55 on its right end. This rod, as may be seen in Figure 1, is inclined to the horizontal and has a horizontal portion 56 which extends through the slot 5| into the interior of the channel 4l so as to be engaged by twenty-five cent coins passing down the channel 4l. A spring 5l has its lower end secured to the rod 54 and has its upper end engaging a stud 58. A stud 59 mounted in the plate 40 serves as a stop to limit the upward movement of the rod 54 and the rod is urged against said stop by means of the spring 5l. An arm 60' has its left end, as seen in Figure 1, journaled on a stud Si mounted in the plate 4Q, and has its right end extending beyond the right edge of the plate 48 and carrying a stud G2. This stud constitutes what is termed a positionable member." A bracket member 53 has offset lugs on each end which are secured to the plate 40 by means of spot welds 64, or in any other suitable manner and the portion between the offset lugs is parallel to and spaced apart from the plate 40 and forms a guide for the arm 50.

A lever member 65 has its upper end journaled on a stud 66 which is mounted in the arm G0. The lever member has an upper portion el of substantial width and a lower portion 65 which is substantially narrower than the portion 6l, and a lower end portion 69 which is narrower than the portion 68, the left edges of the portions 68 and 69 having a curved surface 13 therebetween. A right angled bracket 'il has a vertical portion which is secured to the plate 49 by means of spot welds 'l2 and has a horizontal portion T3 which has an elongated slot formed therein through which the lower end E9 of the lever member 65 extends. The upper portion 5l of the lever member has an elongated hole 'i4 formed therein to lighten it, and below this hole is formed a ratchet slot i5 which is in eiect a follow cam having lands 16 and l1 formed therein. TheI lever member 65 has a stud 18 mounted thereon to which one end of a spring 'i9 is secured.

A lever 8l) carries on its right end, as seen in Figure 1, a stud 8l which extends into the ratchet slot 'I5 and which normally engages the land 16. The lever intermediate the ends thereof has a stud 82 upon which is journaled the lower end of a lever 83. The spring 19 described above has its other end connected to the stud S2 and thus the lever member 55 is urged in a clockwise direction about its pivot 66 and thereby the land 76 is no1'- mally maintained in engagement with the stud 8|, and when the lower end 69 of the lever member 65 is displaced by the end 55 of the rod 54, the stud 8l engages the land T1, thus the stud 8l and the ratchet slot 15 constitute an escapement. The stud 82, in addition to having an upstanding portion upon which the lever 83 is journaled, has

anv extension 82a which extends through an arcuate slot 84 formed in the plate 40. The plate 40 has a rectangular hole 85 formed therein through which the lever 83 extends. The lever 83 has an offset portion 86 which extends through the hole 85, and it has a vertical portion 8l on the side of the plate 40, as seen in Figure l, and a second vertical portion 88 on the side of the plate, as seen in Figure 3. The upper end of the portion 88 is journaled on a stud 89 carried 'by a lever 90 on the opposite face of the plate 40. The lever 90 has one end journaled on a stud 9| mounted in the plate 40. A stud 92 is carried by the other end of the lever 90 and has journaled thereon the upper end of a lever member 95.

The lever member 95 extends generally downwardly on the face of the plate, as seen in Figure 3. Secured to the plate 40 is a bracket having a vertical portion 93 which is secured to the plate in any suitable manner, for example, by spot Welds 94 and this bracket has a horizontal portion 96 which has a slot formed therein in which the lower end of the lever member 95 forms a Working t.

A plate member 9| is journaled on a stud 98 on the plate 40 and it has an upturned ear 99 to which one end of a spring is secured. The other end of this spring is secured to the horizontal portion 96 of the bracket. The plate member 97 has a lug portion I0| to which is secured a rod |02. A stud.|03 mounted in the plate 40 forms a stop against which the rod |02 is normally held under the urge of the spring |00. The plate member 91 also has an upturned lug |04 which is positioned in a Aratchet groove formed in the lever member 95. This ratchet groove has lands |06, |01, |08 and |09 formed therein with which the lug |04 cooperates. Normally the lug |04 is in engagement with the land |06 and it engages the other lands in accordance with the number of dimes passing through the coin passage I I. A plate I I0 is supported in spaced relation to the plate 40 and this plate and its supports form a coin passage to receive dimes. The end |2 of the rod |02 extends into the passage |||lso as to be actuated by the impact of coins moving downwardly in the passage ||I. A bracket has a vertical portion |I3 which is spot welded or otherwise secured to the plate 40. This bracket has a horizontal portion ||4 which has formed therein a guide slot. A lever member ||5 has its lower end journaled on a stud ||6 carried on the left end of the lever 80 (as seen in Figure 1).

The lever member 5 has a portion which is on the side of the plate shown in Figure 1, an angular portion I 8 which extends through a hole I9 formed in the plate 40, and a vertical portion which extends upwardly on the face 0f the plate 40, as seen in Figure 3. The upper end of the lever member ||5 extends through the slot above described as formed in the horizontal portion H4 of the bracket. Thereby the upper end of the lever member I I5 is guided by this bracket. The portion of this lever has a stud |2| mounted thereon and a spring |22 has one end connected to the stud |2|, and the other end is connected to the stud 82 on the lever 80 so that this spring urges the lever member ||5 in a clockwise direction, as viewed in Figure l, Which is a counterclockwise direction, as Viewed in Figure 3. A series of notches |23 is formed in the lever member ||5 and these notches are urged by the spring |22 into engagement with the left edge of the slot formed in the bracket, as viewed in Figure 3 and thereby the notches and said edge of the slot cooperate to form an escapement.

A stud |24 has journaled thereon a plate member |25 which has an upstanding lug |26, which is adapted to engage the upper end of the lever member ||5 and moves the same in a clockwise direction, as viewed in Figure 3, so as to disengage one of the notches |23 from the bracket portion H4. The plate member |25 has a downwardly projecting portion |2 to which a rod |28 is secured. 'I'he rod |26 has a portion |29 which extends vertically downwardly and formed integral with this portion is an angular portion |30.

A spring |3| has one end secured to the plate member |25 and the other end secured to a stud |32 mounted on the plate 40. The spring 3| connects to the plate member above its pivot, and consequently the rod |28 is urged in a counterclockwise direction and the lower end rests against a spacer member |33.

A channel I 34 has flanges |35 and |36. The ange |35 is secured to the plate 40 by spot welds |37, for example, and the flange |36 is secured to the plate 4|) by means of screws |38 extending through the spacer |33, plate ||0 and its spacer, thereby providing between the channel |34 and the plate ||0 a passage |39 for nickels. Since the angular portion |30 of the rod |28 extends into the passage |39 it is actuated by the impact of nickels passing through the passage |39.

A plate 40 has spaced mounting holes |40 and |4| adapted to engage supports in a machine in which the coin controlled mechanism is to be mounted. Spaced apart from the holes |40 and |4| is a hole |42 adapted to engage a shouldered stud in a machine in which the plate 40 is to be mounted so that the plate may be secured thereto by means of a screw and washer (not shown).

Referring to Figures 4 5 and 10, two coin controlled mechanisms, such as that shown in Figures l, 2 and 3, are employed, and the positionable member 62 of one of them is pivotally connected to a link |43. rlhe link |43 has a struck out tongue |44 to which the lower end of a spring |45 is connected. The upper end of the spring is connected to a hook |46 formed on a lug |41 which engages a groove formed in the stud 62. A bar |98 has a lug |99 secured to the upper end thereof which has a hole formed therein, and a boss |5| carried by the link |43 forms a working t in the hole |50 and is retained therein by a clip member |52. The bar |48 has a rack |55 formed therein and this rack is reciprocally carried in a channel |54, which is in turn mounted in a U-shaped channel |53.

The positionable member 62a on a second coin lcontrolled mechanism, like the one shown in Figures 1, 2 and 3, has a link Ifi3a the upper end of which has a hole therein journaled on the stud 62a and retained thereon by means of a clip |4'Ia having its lower end in the form of a hook |46a. The link |430'. has an ear Ilma, and the spring lflia has its upper end connected to the hook |46a and its lower end connected to the ear |44a. Thus the clip |4'Ia is maintained in engagement with a groove formed in the stud 62a.

A bar I48a has a lug |49a secured to the upper end thereof, which has a hole like the hole |50 formed therein and a boss |5|a carried by the link |43a forms a working iit with said hole and is retained by a clip member |52a. The bar |48a has a rack |55a formed therein and this rack is reciprocally carried in a channel |56 which is in turn mounted in a U-shaped channel |53 so that 7 the channels |59 and |56 have their open ends facing each other.

A metallic block member |51, which due to its mass constitutes a weight, is reciprocally carried in the channel |53 and it carries a stud |58 upon which a pinion |60 is journaled. This pinion meshes with both the rack |55 and the rack |55a. The stud |58 has a groove formed therein which is engaged by a clip |59. The clip |59 has its lower end in the form of a wide hook ISI to which the upper ends of springs |62 and |63 are secured.

A connecting rod generally designated by the numeral |65 has an elongated slot |66 formed in the upper end thereof which slidably engages the stud |58 and which is located fore-and-aft between the clip |59 and a hub |61 on the pinion |60. rlhe connecting rod |65 has near the other end a horizontal portion |68 which joins an end portion |69 which is parallel to the main body of the connecting rod |65. The horizontal portion |60 has holes in opposite edges which are engaged by the lower ends of the springs |62 and |63 so that the connecting rod |65 is urged upwardly by the springs |62 and |93, and thereby the lower end of the elongated slot |66 is maintained in engagement with the stud |53. The channel member |53 has secured thereto, for example, by spot welding a bracket member which may be secured to a supporting part of the machine in which it is mounted by means of screws |12.

A crank member |15 is journaled on a stud |16 and carries a stud |11 upon which a hole formed in the lower end |69 of the connecting rod |65 is journaled. The crank member has a radial slot |'l3` formed therein; and a bar |14, reciprocally mounted in the frame of the machine and constituting what might be termed a price bar, extends across all of the columns 0f the machine. This bar is moved in steps and its position represents a credit set up in the machine as a result of all of the coins entered into either one or both of the coin controlled mechanisms, as will hereinafter be more fully explained.

The bar |19 carries a stud |18 which engages and forms a working rlt with the radial slot |13. The crank member |15 has a hub |19, and the stud |10 is secured to an extension |1|a of the frame |1|.

The block member |51 has secured thereto a depending arm |80 which has an oilset portion |6| formed integral therewith, the purpose of which will be presently described. The frame member has a plurality of stepped rectangular perforations |62 formed therein, and these form clearance holes for the push buttons for the several columns of the machine which are disposed in a row adjacent to the price bar |14.

Referring now to Figures 6, 7, 8 and 9, a scavenger and coin tester |93 is positioned above one of the coin controlled mechanisms 40 and the second coin tester and scavenger |83a is positioned above the coin controlled mechanism 40a. The scavengers and testers are supported on a bracket |96, for example, by means of screws |85, and positioned below the left hand sides of these testers and scavengers is a receptacle |66 which receives the coins rejected by both of the scavengers and testers. The receptacle |86 tapers downwardly so that the bottom edge |86a is inclined substantially for the purpose of delivering such coins to a chute |61 via which the coins are returned to the purchaser. The side walls |88 of the receptacle |96 have vertical corrugations |89 formed therein to encourage the coins to keep 8 rolling, thereby preventing them from becoming lodged in the receptacle.

The bracket |84 in which the scavengers and testers |83 and |S3a are mounted has secured thereto by means of screws |9| a lever |90, and the bracket |84 is adjustably supported on a frame in the vending machine so that the bracket |84 may be leveled independently of the rest of the machine, regardless of how the floors slant in any building in which the machine is located. For adjusting the level of the bracket |04 screws, such as the screw |92, for example, are provided.

Between the coin scavengers and coin testers and the coin controlled mechanisms 40 and 40a are positioned members, such as the member |93, which include coin passages for the several sizes of coins. For example, in the arrangements shown in the drawings the twenty-live cent coins are delivered to the coin chute 4| on the coin controlled device, the dimes are delivered to the coin passages in the coin controlled mechanism, and the nickels are delivered to the chute |39. The member |93 is secured to the coin controlled mechanism 40a, for example, by means of screws |94.

A stud |95 on the frame carries a bell crank |96- which has an arm |91 carrying a stud |98 upon which is journaled a bearing hole formed in the lower end of the connecting rod |99. This connecting rod extends upwardly and its upper end is journaled on a stud 200 carried by a lever 20| which is journaled on a shaft 202 carried in a bracket 203, which is secured to a frame member 204. The lever 20| carries a stud 205 on its outer end upon which is journaled a roller 206. The lever 20| isfiXedly connected to a second like lever 201 which carries a stud 208 upon which a roller 209 is journaled. When the coin return is operated by the purchaser, to get his money back, as will presently be described, the connecting rod |99 is moved downwardly causing the rollers 206 and 209 to move downwardly and actuate the scavenger-testers |0311 and |83 respectively to cause them to eject into the receptacle |06 any coins or the like remaining therein.

The bell crank |96 has'an arm 210 the outer end of which carries an engaging member 2|| which engages the end |6| of the depending arm for raising the metallic block |51 of the differential and thereby effecting the resetting of both the coin controlled mechanisms 40 and 40a.. The bell crank |96 has an arm 2|2 extending upwardly, the upper end 2| 3 of which is reduced in dimension and engages a slot 2H formed in a sliding member 2|5. The sliding member has an upturned end 2|S which is adapted to be engaged by a coin return button 2|1 reciprocally carried in a front frame member 2|8, a spring 2|9 being provided for returning the coin return button 2 |1 to its normal position each time it is depressed and released. A frame member 220 has a guide slot 22| formed therein and a stud 222 carried by the sliding member 2|5 extends through this slot and is guided thereby. A frame extension 223 has a rectangular slot 224 formed therein through which the sliding member 2|5 extends and with which it forms a working nt.

Spaced apart axially on the stud and movable with the bell crank |96 is an arm 225 which carries a stud 226 upon which is pivotally mounted a member 221. The member 221 has an arm 228 which has an angular end portion 229 which is adapted to engage the notched end 230 of a lever 23|. The member 221 also has an arm 235 the outer end 236 of which is curved somewhat in the form of a hook. Cooperating with the arm is a roller 231 which is journaled on a stud The lever 23| is journaled on a stud 232 and has a tail portion 233 which cooperates with a stud 234. A lug 239 formed on the member 221 has a hole therein to which one end of a spring 240 is attached. The other end of this spring is attached to a stud 24| on the plate of the coin control 40a so that thespring tends to urge the member 221 in a counterclockwise direction about the pivot 226.

The member 221 has a curved arm 242 formed integral therewith which carries on its outer end an engaging member `243 which is adapted to engage and depress an extension 244 formed on a shaft 245, as may be best seen in Figure 8. The shaft 245 has its left end 246, as seen in Figure 8, angular with respect to the main portion of the shaft, and between the end 246 and the extension 244 the shaft 245 vis journ-aled in a hole formed in the frame extension 223 which is secured to a frame member 248. A bracket member 249 secured to the frame member 248 has extending into it from the bottom end thereof a V-shaped notch 250. The shaft 245, Figure 9, is urged into working engagement with the apex f the V- shaped notch 250 by means of springs 25| and 252, having their lower ends secured to a shaft embracing clip 253. The other ends of the springs 25| and 252 are secured to a' bracket 254, as may best be seen in Figure 6.

n A coin basket 255 is secured on the frame in nxed relation to the coin controlled mechanism and 40a. This basket is generally in the form of a hollow inverted frustrum and the lower end thereof is open and provided with a closure member 256 having side anges 251 and 258. The

closure member 256 is secured on the flattened end 259 of the shaft 245 by spot Welding or any other suitable means. The function of the shaft 245 and the closure member 256 is two-fold. When the coin return button 2 1 is depressed the shaft and the closure member 259 thereon are rotated in a counterclockwise direction, as viewed from the left side of Figure 6, so that the coins in the basket 255 are discharged into a passage (not shown) which leads to the article delivery receptacle (not shown). The other function is effective when the machine is operated to deliver an article, and during the delivery of the article the shaft and the closure member 256 are rotated in a clockwise direction, as viewed from the left side of Figure 6, thereby dumping the coins into a passage which leads to an accepted coin receptacle (not shown) in the base of the machine.

Operation of the com controlled mechanisms Since the coin control is dual, and due to the differential arrangement between them and the price bar |14, all of the coins involved in the transaction may be inserted in either one of the coin controls 40 or 40a, or some of the money can be placed in one and some in the other. For example, if twenty-ve cents is to be put into the machine and this is in change, twenty cents could be p-ut into one of the coin controls and five cents in the other, or fifteen cents in one and ten cents in the other.

-When a coin, for example a nickel, is placed in one of the coin controls, for example the coin control 40, it passes down the passage |39 (Figure 3)and by impact against the end |30 of the rod |28 causes the lever to move in a clockwise direc- 10 tion on the axis |24,` thereby disengaging one of the notches |23 from the bracket portion |I4. Now since the lever member ||5 is fulcrumed at ||6 to the lever 80 and since the lever 80 is fulcrumed at an intermediate point at 62, this upward motion of the lever member ||5 is changed to a downward motion of the other arm 60 by the lever 80, and this is imparted to the arm 60 via the arm 65, thereby causing the stud 62 to move downwardly an increment of movement representing ve cents. This movement may be imparted directly to the price bar |14 by any common form of linkage. However, in the embodiment shown, where two coin controls are emi ployed, the studs` 62 move differential mechanism,

such as that shown in Figures 4 and 5, the operation of which will be presently described.

It will be understood that if two nickels pass through the passage |39 the lever member ||5 moved upwardly twice for a sum of two notches, or if more nickels are passed through the passage |39 the lever member ||5 is moved upwardly a corresponding number of notches.

Now suppose a. dirne is inserted via the passage It strikes the end of the rod |02, thereby moving it in a clockwise direction about its fulcrum 96. As this occurs the lug |04 in the ratchet groove |05 on the lever member 95 is also swung in a clockwise direction and disengaged from the This causes the lever member 95 to move downwardly, and as the spring |00 urges the lug |04 in a counterclockwise direction it is immediately pulled into position to arrest the land |01, with the result that the lever 95 is 'moved down from the land |06 to the land |01.

This lever through the pivotal connection 92 causes the lever 90 to move in a. counter-clockwise direction about the fulcrum 9|.

Now the lever 90 through the lever 83, which is fulcrumed thereto at 89, causes the lever to swing in a counter-clockwise direction about the fulcrum H6, and the movement is thence imparted to the lever l60 via the lever member 65 in the same manner as described above for the nickel. It will be noted that when the control is actuated by a nickel the lever 80 is fulcrumed at 82, whereas when the control is actuated by a dime the lever is fulcrumed about the fulcrum ||6. In the case of the dime the lever 80 is fulcrumed about H6, and consequently its opposite end moves twice as far (a space equal to two five cent increments), and this motion of course is transmitted to the arm v60 via the lever member 65.

If two dimes are sent down the passage the first one causes the lever member to move downwardly from the land |06 to the land |01, as just described. When the second dime is inserted it causes the lever member 95 to move downwardly from a point where the land |01 is engaged by the lug |04 to a point where the land |08 engages it. A third dime would cause the lever member 95 to move still further downward to a point where the land |09 engages the lug |04.

When a quarter is passed through the passage 4| it engages the end 56 of the rod 54 and by impact causes the lug 53 to swing in a counterclockwise direction about the fulcrum 52, with the result that the up-turned portion 55 thereon -acts against the curved surface 10 on the lower portion 66 of the lever member 615, thereby causing the lever member 65 to swing in a counter-clockwise direction (Figure l) about the fulcrum 66. This causes the land 16 to become disengaged from the stud 8| and allows the lever 11' member 65 to move downwardly until the land 11 thereon engages the stud 8| and is arrested by it. The spacing of the lands 16 and 11 is such that the stud 62 carried in the lever 60 moves down a distance equal to iive of the nickel increments.

From the above description it will be evident that nickels alone, dimes alone, quarters alone, or combinations thereof, will actuate the coin control and that the movement of the lever 60 carrying the stud 62 will be in increments (each of which is equal to the length of movement representing a nickel) depending on the amount of money inserted.

. Now Where two such coin controls are employed, the arrangement is shown in Figures 4 and 5. Linked to the lever 66 through the medium of the stud 62 is a rack |48 having teeth |55. Linked to the second coin control lever is a similar rack |48a which has teeth |55a. Now the teeth of these racks face each other, and between them and meshing with both of them is a pinion |60 which is carried on a slidable block |51 which also constitutes a weight.

Now referring to Figure 5, if coins are inserted in the left hand coin control the rack |55 is moved downwardly thereby, and since the rack |55a is immobile the pinion rolls along the teeth y |55@ and also moves downwardly. Through the link |68 the crank member |15 is moved on its fulcrum |16, thereby causing the price bar |14 to move.

If the coins are inserted in the right hand coin control the rack |55 connected to the left hand coin control remains stationary, and the teeth of the pinion |60 roll along the teeth |55 as the rack |48a. moves downwardly, and through the medium of the link |68 the crank |15 is rotated.

If some cf the coins are inserted in one coin control and some in the other, each coin indivdually eects a downward movement of the pinion |60, the link |68 and a rotation of the crank |15.

From the above it will be quite evident that the coins may be inserted in either one of the ycoin controls or that some of them may be inserted in one coin control and some in the other, and the samev eiiective result Would be obtained in either case.

At the end of a vending operation the depending arm |80 is raised upwardly during the resetting operation, and thereby the weight member |51 and the pinion |60 are elevated to their normal positions.

Referring to Figure 6, it will be noted that the depending arm |80 and its offset portion |8| are in cooperative relation with the horizontal extension 212 of the arm 21|, as hereinafter de,

scribed in connection with Figure 6.

Other ,features of the machine The machine has a main shaft 26,6v which is rotated through an arc and returned to its normal position during each operating cycle by means of mechanism shown in Figure 1 3.- and which will presently be described. Fixed o n the shaft 260 is a lever 26| which has an engaging surface 262 which engages the right angled portion 246 of the shaft 245 and moves the shaft 245 and the member 256 in a clockwise. direction, as viewed from the left side of Figuresl 6, 8 or- 9, thereby causing. coins from the basket 255 to be delivered to the accepted receptacle. 26| has a lug 263 thereon to one end of which a spring 264 is secured.

The levery A bell crank 265 has a depending arm 266 with a hole 261 adjacent to the end thereof. One end of a spring 268 engages the hole 261 and thev other end of the spring is secured to a fixed boss 266 on the frame of the machine. The arm 2165 has an ear 210 formed integral therewith and the other end of the spring 264 engages this ear and urges the bell crank 265 to a point where its other arm 21| normally abuts the lug 263. The arm 21| has a horizontal extension 212 which engages the depending arm and resets the differential, the two coin controlled mechanisms 40 and 46a connected thereto, and the price bar |14. When the machine is operated to deliver an article the shaft 266 moves rst in a clockwise direction, as viewed from the end seen in Figure 6, and consequently the arm 26| and the bell crank 265 move therewith because the arm 26| is keyed on the shaft 260 and the bell crank 265 is held against the lug 263 by the spring 264 and this movement is abetted by the spring 268. As the shaft is rotated in a clockwise direction, as state above, the surface 262 engages the angular end 246 of the shaft 245 and causes the acceptance of the coins. Since the bell crank 265 is following the movement of the arm 26|, the extension 212 on its arm 21| engages the depending member |80 and resets the mechanisms and the price bar, and it does it under the urge of the spring 2168 and the urge of the spring 264 because by this time the arm 26| has advanced to a stage where the lug 263 has moved out of contact with the arm 21| in effecting the delivery of the article. After the delivery of the article the shaft 260 rotates through an arc in a counterclockwise direction, as viewed from the end shown in Fig-A ure 6, and the arm 26| and the bell crank 265 are returned to their normal positions which are the positions shown in Figure 6.

Referring now to Figure 10, the differential mechanism is shown partly broken away, and the. connections to the price bar |14 are shown. The. price bar |14 has a series of notches 213, 214, 215 and 216 formed therein. These notches are engaged by key plates such as the key plate 211 carried on the selector push buttons such as push button 21/8 shown in Figure 11. Paralleling the price bar |14 is a lock-.out chain gen. erally designated by the numeral 286. This chain has a confined space between two end bar. riers 216 and 28|. with which aligned slots 282, 283, 284, 285 communicate. These slots are formed 'in side walls 286. and 281", which also form. guides for a series of slidable members 288, 289, 290, 29|, 202i and 293. Each ofl these slidable members has. a bevel 294. formed at one end thereof and a bevel` 205 formed at the other en d, so that when they are placed in an area within the space between thel side Walls 286 and 281 andthe end barriers 210 and 28|, the. beveled surfaces 29,4 and 205. match beveled surfaces 266, and 291 on a plunger 298 which is also mounted on the push button 2-18 and which is movable therewith.

When the push button 218 is depressed or pushed in the beveled end 296, 291 engages oney or the other or both of the beveled surfaces 294 and 2,05, forms an entering wedge and enters between the adjacent ends of any two of the movable members 269 to 2,93. In Figure 10v this plunger is sho-wnv positioned between the slidable members 2,90'and; 20 t, and when the plunger is. so positioned all of the space betweenA the barriers 219.and= 281|. is. occupied by the several,

V13 slidable members and the plunger, and therefore no other plunger on any other push button in the machine can enter between the other movable members of the chain after a first one has entered.

The lock out chain 233 is shown in Figure 11 as positioned on a bracket 203 secured to the frame member |1Ia. The price bar |14 is slidably mounted in a bracket 300 which is also secured to the frame member I1Ia. The bracket 300 has perforations or openings 30| formed therein in alignment with the key plates 211 carried by the4 push buttons 218, so that said plates may pass through the same and engage one of the notches formed in the price bar I 14. The plates 211 have forms which may be compared by referring to Figure 16. The key plate 211e has a tab extension 400 which is tangent to one edge thereof and spaced apart from the other edge. AWhen the tangent edge is on the right this key plate represents five cents; when it is turned over so that the tangent edge is on the left it represents twenty-five cents. The key plate 2112 has a tab extension 400e the same width as the tab 400 by being notched out at 40| extending in from one` edge and at 402 extending in from the other edge. When the key plate is positioned with the narrow notch to the right it represents ten cents, and when it is placed with the narrow edge to the left it represents twenty cents. The key plate 211a has equal notches 403 formed therein from each edge thereof, leaving a tab 40012 centrally located thereon and this key plate represents fifteen cents.

The push button is slidably mounted in a socket 302 which extends through an opening formed in the frame I'Ha and which is secured thereto by means of escutcheon pins 303. The main shaft 260 has secured thereto by means of a rivet 304 a metallic stamping having a portion 305 which partially embraces the shaft 260, having an extension 303 the front portion 301 of which is in the form of a curved plate. Coextensive with the portion of the extension 303 is a bracing plate 308. A second bracing member 309 formed integral with the portion 305 has its extremity 3I0 in contact with the extension 303 in an area spaced apart from the bracing means 308. Opposite the extremity 3I0 is a bracket member 3| I and this bracket member and the extremity 3I0 may be spot welded to the extension 300. The curved portion 301 has a rectangular opening 3I2 formed therein which is adapted to be4 engaged, during a delivery operation, by a hook 3 I 3 formed on the end of an arm 3I4.

A rectangular plate member 3I5 has upturned edges and channels parallel to the edges (not shown) between which the arm 3I4 is pivoted. Secured to the arm 3I4 is a hub member 3I6 which is journaled on a shaft 3 I1 carried in the rectangular member SI5. The rectangular member has secured to its lower end a pair of spaced arms one of which is designated by the numeral 3I8 and these arms have their extremities embracing and journaled on the main shaft 260 so that they are freely movable thereon. The member 3I5 also carries a tab 313 which forms a stop against which the arm 3|4 may normally rest. Extending downwardly from the hub 3I6 is a curved tail 320 which is actuated by the angular tip 32| of a bar 322 which forms an integral part of the push button 213. Extending from the upper end of the plate 3I5 is a pair of curved brackets one of which is designated by the numeral 323 and secured to these brackets is rafcurved plate 14 324 which preferably has its engaging end 325 serrated.

Extending all the way across the machine beneath the push buttons is a rock shaft 326 which has an embracing member 321 thereon. This embracing member has an extension 328 which is angular with respect to the vertical when the shaft 326 is in its normal position and which is moved from its normal position by means of a screw head 329 carried on the bottom edge of the push button assembly.

Secured on the outer end of the shaft 326, as may be seen in Figure 13, is a bell crank 330 which has an arm 33| with an upturned tab 332 formed thereon to which one end of a spring 333 is secured. The other end of the spring 333 is connected to a stationary post 334. The bell crank 330 has an arm 335 which carries a stud 336. Journaled on this stud is a bearing hole formed in one end of a bar 33|?v and this bar is retained on the stud 333 by means of a spring clip 339.

Returning to Figure 11, the machine has a second shaft 340 which is embraced by member `34| having its extremities abutting each other to form a continuous radial arm 342. The arms 318 shown in their normal positions in Figure 1l are urged to this normal position by -means of springs 343 secured to the arms and to the frame member Illa. Carried on the outer end of the shaft 340, as may be seen in Figure 13, is a crank 344 which has an end 345 bent at right angles to the main body of the crank and this comes to rest against a member to be presently described. The crank 344 has an ear 346 with a hole through which is engaged by one end of a spring 341. The

other end of this spring is connected to a fixed post 343 so that the spring continuously urges the crank 344 and consequently the shaft 340 and the radial arm 342 thereon to their normal positions.

Referring againto Figure 11, since the crank just described maintains the shaft 343 and the radial arm carried thereby to the position shown in Figure l1, it can be seen that when the push button 218 is depressed the end 32| of the member 322 which forms an integral part of the push button engages the curved tail 323 and swings the arm 3I4 upwardly so that the hook end 3I3 thereof enters the opening 3|2 and engages the curved member 301, so that when the shaft 260 is rocked in a counterclockwise direction, as seen in Figure 11, to deliver an article and rocked in a clockwise direction to again assume its normal position, the article ejector 324 moves therewith and ejects the article.

Figure 12 shows the shaft 260 swung almost its entire stroke in the counterclockwise direction, thereby ejecting an article 349 from the article column 350. As the article delivery stroke is completed and the mechanism is returned to its normal position the crank 344 is moved through an arc in a counterclockwise direction with the result that the end 32| which, during the delivery and return operation, was engaged by the ends of the arm 342, is released from these ends due to said arcuate movement of the shaft 340. As soon as the end 32| is released the push button returns to its normal position, which is the position shown in Figure 11.

Referring again to Figure 13, the bar 333 reciprocates in a suitable slot 35|a formed in a plate 35|. The bar 338 near the lower end thereof has preferably formed integral therewith a lateral tab 33811 which extends beyond the end 352 of the bar 33B so that the end 352 constitutes an engaging member.

The crank member 353 which is mounted on a shaft 354 has an ear 355 extending across the path of the bar 338 and adapted to be engaged by the engaging end 352 of the bar 338. Carried on the shaft 354, not shown, is a mercury switch such as that shown in copending application Serial No. 65,590, led December 16, 1948, which when rocked connects an electric motor such as that shown in said copending application and thereby eiects, through the medium of a one revolution clutch, the rotation of a shaft 356 upon which is secured a disc 351 carrying a stud 358. The stud 358 is parallel to the shaft 356 and has `iournaled thereon a bearing hole which is formed in one end oi a curved connecting rod 366. The end of this connecting rod is retained on the stud 353 by means of a spring clip 355. The other end of the connecting rod 366 has a bearing hole formed in it which is journaled on a stud 35| which is carried on a dog 362. The dog 362 has a hub 363 which is keyed on the shaft 263. Formed integral with the dog 362 is a tab 364 which extends forwardly, as seen in Figure 13, and normally in contact with this tab is a lever 365 which has one end journaled on a stud 366, which is carried on a member 361, which is journaled on and freely movable on the shaft 266. The member 361 has a tab 368 thereon to which one end of a spring 369 is connected. The other end of the spring is connected to the stud 334 and thus the member 361 is urged by this spring in a counterclockwise direction, as seen in Figure 13. The member 361 has a downwardly projecting ear 310 which bears against the right hand edge of the lever 365 and, due to the urge of the spring 363, urges the left edge of the lever 365 against the tab 364.

The member 361 has a depending arm 31| which carries a forwardly projecting ear 312. The right edge of the arm 31|, as seen in Figure 13, has a curved depression 313 formed therein which cooperates with the post 334 in a manner to be presently described.

The angular end 345 of the crank 344 is normally in contact with the surface 314 of the member 361.

The lever 365 has an elongated slot 315 formed therein adjacent to the upper end thereof, and forming a working fit in this slot is a stud 316 having an enlarged head 311. The stud 316 is secured to a bar 313 the left end of which forms a working fit in a slot formed in an annular bracket 315. The other end of the bar 318 is reciprocally carried in an elongated slot. 386 formed in a lug 33| supported on the frame of the mechanism. The slot 363 is substantially longer than the width of the bar 313 so that it not only reciprocates therein but also moves laterally (up and down, as seen in Figure 13). A spring 332 has one end extending through a small hole 383 formed in the right end of the bar 318 and the other end of this spring is connected to a lug 384 which is xed on the frame of the machine. The bar 313 has a depending extension 335 with a laterally extending tab 386 formed integral therewith.

When a push button, such as the push button 218, for example, is depressed, the screw 328, as pointed out before herein, engages the extension 323 of the member 321 which embraces the shaft 326 and thereby causes the shaft to rotate through an arc in a counterclockwise direction. The bell crank 330 moves therewith, since it is keyed to the shaft 326 and the bar 338 is moved lengthwise and it causes the shaft 354 carrying a mercury switch (not shown) to rock to a position where the mercury switch is closed, thereby supplying power to the electric motor. The shaft 356 is rotated, through suitable gearing and a one revolution clutch, a single revolution in a counterclockwise direction, as Viewed in Figure 13, thereby through the medium of the connecting rod 360 causing the dog 362 to move counterclockwise through an arc and return to its normal position, and thus the shaft 260 is rocked to eifect the delivery of an article in the manner described in connection with Figures l1 and 12.

[as the dog 362 starts moving in a counterclockwise direction rthe member 351 and the lever 365 move therewith until the depressed surface 313 on the member 361 comes in contact with the post 334 and from there on the member 361 is arrested. During this movement the bar 31B is moved to the left., and since the tab 336 is angularly disposed on the bar it cams over the price bar |14, and after it passes over the price bar the right end of the bar 318 is pulled downwardly by the spring 382 so that the tab 366 and its extension 385 remain on the left side of and in contact with the price bar |14.

When the push button is depressed and released before the cycle has been completed the member 331 and the lever 365 move with the dog 362 as the latter' is moving in a clockwise direction to return to its normal position, and the tab 364 acting against the lever 365 and the lever in turn acting against the lug 31|) causes the member 361 to move positively, against the urge of the spring 369. The surface 314 of the member 361 engages the portion 345 of the crank 344, thereby rotating the shaft 340 in a counterclockwise direction and releasing the end 32| of the push button member 322 from the radial arm 342 on the shaft 346, thereby releasing the push button 213 and withdrawing the plunger 298 from the lock out chain and the key plate 211 from one of the slots in the price bar |14. This allows the push button to return to its normal position and consequently its screw 326 is disengaged from the extension 323 and allows the bell crank 330 and its shaft 326 to return to its normal position under the urge of the spring I333` Since by this time the price bar |14 has returned to its normal position, the tab 336 is free to return to its normal position under the urge imparted to it by the lever 36. Thus everything is reset for a subsequent operation.

Assuming that the push button is depressed and is held in by the operator the cycle starts as described above and continues to the point where the radial arm 342 releases the portion 32| of the push button member 322, but the key plate 211 is still engaged with one of the notches in the price bar |14, and also the lock out plunger 298 is in engagement with the lock out chain. In addition to this the extension 323 on the shaft 326 is held in advanced position by the screw 329 on the push button assembly; therefore the bar 338 cannot return to its normal position, so that as the member 361 is moving in a clockwise direction due to the clockwise motion of the dog 362. The tab 364 acting against the left side of the lever 365 therefore acts as a fulcrum, and since the bar 318 cannot move due to the fact that the price bar |14 has not withdrawn, the result is that the member 361 is moved a greater distance than it normally is, so that the end 312 engages and lifts the bar 338 to the upper end of its slot in the member 35| and thereby its engaging end 352 held out of the range of the tab 355 and the 17 mercury switch on the other end of the shaft 354 cannot be actuated.

These elements remain in this relation as long as the push button is held in. Now, if the absentminded purchaser happens to think that he is holding the button in and releases it, the plunger 298 is'withdrawn from the lock out chain and at the same time the key plate 211 is withdrawn from its notch formed in the price bar |14 and, therefore the price bar can return to its normal position and in doing so its end clears the tab 386, allowing the bar 318 to move to the right to its normal position, and in so doing the member 361 through the medium of the lever 365, its slot, and the stud 316 therein allows the member 351 to return to its normal position, allowing the bar 338 to return to its normal position within the slot in the member 35|. Since the release of the push button allows the screw 329 to become disengaged with the Aextension 328, it and its shaft 326 together with the bell crank 33E) are allowed to return to their normal position and therefore the engaging member of the bar 338 is withdrawn to its normal position with the engaging end 352 spaced apart from the tab 355 on the crank member 353 and thereafter the machine may be perated by inserting coins therein in the usual manner. i

It will be evident that if the push button had been held in and anybody attempted to push in any other buttons they would be prevented from doing so because the lock out chain is filled by the plunger 298 and therefore no other plunger can enter it. It would also be prevented from operating because the bell crank 330 had not returned to its normal position to re-engage the tab 355 on the crank 353, and due to the additional fact that the left end of the bar 338 is raised so that its engaging end 352 is out of the range of the tab 355 on the crank 353 and therefore it is impossible to operate the machine by holding one of the push buttons depressed and attempting to operate another while so holding the rst one.

The above description, while it has no direct bearing on the coin controlled devices per se, is explained in View of the fact that it does directly affect the price bar, the movement of which is controlled by the coin controlled devices.

It will be noted that all of the elements of the coin controlled devices are formed of stampings which can be made on a plunger press and of studs which may be produced in large quantities very cheaply on screw machines, and since dies for punching out these elements can be made very accurately, the result is the production of precision coin controlled devices in great quantities and at low cost.

It is to be understood that the above detailed description of the present invention is intended to disclose an embodiment thereof to those skilled in the art, but that the invention is not to be construed as limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of being practiced and carried out in Various ways without departing from the spirit of the invention.
